I accidentally erased the internal SD card after a chmod catastrophe shortly after getting my DreamPlug. At the moment I have the card reloaded with the uImage on one partition (FAT16) and the root file system (from the DreamPlug download site) on another partition formatted as EXT2. On the rare occasion that my jtag unit does make a serial connection between the DreamPlug and my mac (After jiggling wires for a half hour or so...) I try to follow guides from the wiki on making the SD card bootable. But it seems like these guides were all written for the GuruPlug and since there's no other plug out there with internal SD I figured the forum was the last place to go before I admit defeat.

Basically: How do I make the internal SD bootable again? And is there any trick to making my jtag connectors make a connection?

What is error message you got when you try to boot? there are no magic setting to make the internal uSD bootable. all setup is in the u-boot environment so as long as you still have your u-boot environment intact than there is no reason why you can not boot.

the last command "bootm ..." should start booting linux, so base on your first post this should be where it failed, please post the command you entered and its output, we will have to check during steps above where it failed.

Also, a better idea of my partition table:/dev/sdc1 --> FAT16 and contains uImage only (Partition is about 100 MB)/dev/sdc2 --> EXT2 and contains the root file system (Partition is 1.8 GB I think or whatever is left of the 2 GB card)

I am little bit confuse, you should not get the "Invalid boot device" message after you have successful run "fatls usb 0 ..." command. did you reset in between the two commands? so let me reiterate sequence
